According to 13F filings submitted to the U.S. Securities and Exchange Commission, Mubadala Investment Company and Al Warda Investments held more than 20 million shares combined in BlackRock’s iShares Bitcoin Trust (IBIT) by the end of 2025. The total value of their positions exceeded $1 billion at year-end.
Mubadala increased its stake by roughly 46% in the fourth quarter, reaching over 12.7 million shares valued at approximately $631 million. Al Warda Investments reported holding more than 8.2 million shares, worth around $408 million. Together, the two funds crossed the $1 billion exposure mark.
Notably, these purchases came while Bitcoin fell about 23% during the quarter. Although the combined value of the holdings declined to around $800 million amid further price weakness in early 2026, the move signals that large institutional investors may be viewing market pullbacks as long-term accumulation opportunities. With roughly $58 billion in assets, IBIT remains one of the largest regulated vehicles for Bitcoin exposure in the United States.
